The HALTI Harness was designed by Dr Roger Mugford to STOP a dog pulling by providing front control. It applies the same principle as the HALTI Headcollar but by steering the dog from his chest rather than by his head. The HALTI Harness puts owners in control of dogs that don’t like or cannot wear a HALTI Headcollar.
The patented front control system steers the dog from his chest and shoulders - and thus sets the direction in which he can move. Unlike other designs of anti-pull harnesses, the HALTI does not put painful pressure on the body and is always comfortable. Ideally used with a double-ended lead to give maximum control. The back ring above the shoulders acts as a brake while the front lead steers.
